Bert Jan Schrijver presented on Malmberg's journey to continuous delivery using open source tools and cloud services. Malmberg is an educational publisher that builds e-learning applications using Java, Vert.x, AngularJS and MongoDB on Amazon cloud services. They faced issues with slow development and operations communication and difficult production problem analysis using a traditional model. To address this, Malmberg established an expert DevOps team, defined key principles like keeping the master branch releasable at all times and managing all automation through Jenkins, and overcame challenges like gaining developer skills and hitting AWS limits to achieve benefits like increased agility, availability and cost reductions.
DevOps is not just a practice, designation or concept, it is a smart collaboration between software developers and IT professionals, DevOps has become a most requirement for all big and mid-size organizations.

Summary:
We are QAs on a lean start-up team. And wanted to share the lessons learned in ensuring quality of the product while being part of a team which was always focused on releasing to production. One of the techniques we use as a lean start-up team is Continuous Deployment. Using CD, we were not only able to deliver usable software to the market faster, but also the foundational principles of CD help us get faster feedback on how reliable our software, in terms of defects, bugs, performance, security. If you carefully look to find out the current need in the software industry, you'll find that there are majorly 2 key elements. One of them being 'How fast can I go-live with my product into the market', i.e. being Faster. And second is 'How perfect is my software? or Can it perform under extreme conditions?' i.e. how reliable is it? This is the topic for our presentation - The faster, smarter and reliable lean start-up QA.
DevOps is a software development method which is all about working together between Developers and IT Professionals. This presentation gives you an introduction to DevOps.

Where Testers and QA Fit in the Story of DevOps
Continuous delivery. CI. GitHub. Scrum. CD. Jenkins. Continuous testing. Continuous integration. These are just some terms that are supposed to describe the word soup that is DevOps. Chances are that you have heard some or all of these words being passed around at your daily stand ups or company meetings.
However, where does QA and testing fit into the story of DevOps? Some would say that developers and operations teams are all you need for a successful DevOps pipeline, while others show that Dev, Test and Ops need to be included to ensure quality at every step in your pipeline.
In this webinar, Ryan Yackel, QASymphony's Director of Product Marketing, and Sunil Sehgal, Managing Partner at TechArcis, will share their experiences as they navigate you through the DevTestOps waters. In this webinar you will learn:
Overview of the State of DevOps
Common misconceptions of DevOps and QA
How testers must adapt to the DevOps process
The tools testers need for continuous testing

Continuous Testing: A Key to DevOps SuccessTechWell
As IT organizations adopt a DevOps strategy, continuous testing (CT) becomes a key ingredient of the DevOps ecosystem. CT enables faster release cycles, more changes per release, upfront isolation of risks, and reduced operations costs. The approach to scale the traditional automation testing infrastructure, test environments, and test data management requires a culture shift using new tools and techniques. Sujay Honnamane discusses a CT strategy for aspiring and already implemented DevOps organizations. Sujay shares examples of tools, techniques, and practical solutions that include continuous integration using the Jenkins CI server, service virtualization through CA Lisa tools, automated code coverage analysis to create impact-based tests, automated test script load balancing for effective use of test environments, and faster test cycles, providing a holistic approach/workflow for CT. Sujay and his teams have successfully implemented CT for several clients in their DevOps journey to achieve a repeatable and highly predictable software delivery process.

Security is tough and is even tougher to do, in complex environments with lots of dependencies and monolithic architecture. With emergence of Microservice architecture, security has become a bit easier however it introduces its own set of security challenges. This talk will showcase how we can leverage DevSecOps techniques to secure APIs/Microservices using free and open source software. We will also discuss how emerging technologies like Docker, Kubernetes, Clair, ansible, consul, vault, etc., can be used to scale/strengthen the security program for free.

Continues Testing: We hear this quote frequently, in small and large companies around the world. My team and I have been a part of this evolution. I was asked to join an ambitious project at work. My task, was to build a team to be the first DevTest group in my organization.
The journey I will share with you is how to integrate the agile mindset into your non-agile team, focusing on methodologies, techniques, and technologies.

This deck represents our current thinking about the best way to build enterprise SaaS software in 2015 - using a variety of techniques from several disciplines.
Since I wrote this I have also become very interested in resilience engineering and the notion that web developers are primarily engaged in the construction of socio-technical systems. When I rewrite this I plan to talk about how we should try to minimize mean-time-to-recover (MTTR) instead of mean-time-between-failures (MTBF), and how continuous deployment grows a safety culture around your operations.
I redacted most of the examples that illustrate these points because they use sensitive code examples or URLs. If you want to see the rest of slides, join us!
Mind the Gap: How to bridge the gap between development and operations with release management
The release management process remains challenging for large IT organizations due to the continuing disconnect between development, QA, and operations teams. The challenge faced by these large enterprises is that process maturity, methodology, and platforms vary greatly across teams, organizations and business units. These challenges often produce gaps between development and operations teams. Release management is still being done, but with very inconsistent results and at a high cost, providing minimal insight and a lack of audit compliance.
Join us as Julian Fish, Director of Products at Serena Software, demonstrates how the unique integration framework and process capabilities of Serena Release Control can deliver a consistent and repeatable process that provides complete traceability, audit and compliance across Waterfall, Progressive and Agile processes, for both ITIL and DevOps approaches, and supporting Mainframe to mobile platforms.
For a beginner, this is a good quality pictorial representation of DevOps and DevOps Center of Excellence.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Approach
How
we
initiated
change.
11. Master branch is always releasable
Principle 1
Every change is developed and tested in a feature branch.
Don’t merge it until it’s done.
12. Unit/integration (Java & JavaScript), mutation, end-to-end (FitNesse/BrowserStack),
Sonar for quality and coverage reporting.
Rely on multiple layers of tests.
Each commit is tested extensively
Principle 2
13. Manage builds, tests, QA and deployments from a single place.
Jenkins as the heart of the delivery process.
Every delivery step is a Jenkins job
Principle 3
14. After deploying 6 new features, when one has an issue, why roll back 5 good features?
Don’t. Just roll out a fix quickly.
Keep moving ahead.
Deployments are roll-forward only
Principle 4
15. No logging in to servers. Need a change or upgrade? Just update the recipe.
Hands off.
Infrastructure as code - for everything
Principle 5
16. The flexibility and resilience is well worth it.
What about using containers? The EC2 instance is our container.
Even when you don’t need to scale.
Put everything in auto scaling groups
Principle 6
17. You can’t explain maintenance windows to modern end users anymore.
Our end users are the Facebook generation.
No downtime in production
Principle 7
18. Make sure you find the problem before it finds you.
Work proactive, not reactive.
Eyes and ears in production
Principle 8
19. Repeating tasks such as viewing logs and doing deployments must be common jobs.
Specialisms are OK, but only for incidental tasks.
Repeating tasks are executable for all team members
Principle 9
20. Differences between teams are OK. A team that’s dependent on external help is not.
Give teams the freedom to work in a way that works for them.
DevOps teams work on a self service basis
Principle 10
21. Don't assume that cultural change
won't be an issue. It will.
Resistance
It turns out that something in
recent AWS Linux kernels triggers
slave disconnects.
We found out the hard way.
Jenkins slaves can be a pain
Not all devs are comfortable with
managing infrastructure and
middleware.
Devs need to step up their game
This kills team progress.
Don’t depend on availability
